So, my friend Chris mentioned that I should check out Songbird for an iTunes alternative.  So, I download it, and a whole bunch of stuff spits out on my screen, and the app doesn’t run.  I see something that looks like:

*** glibc detected *** ././songbird-bin: free(): invalid pointer:
0x00007f203935a8d0 ***

Hrm. after searching around, I find out that the libvisual plugin package is to blame. So, I remove it:

$ sudo apt-get remove libvisual-0.4-plugins

And it works! Just thought I’d pass this along in case someone else runs into this issue.  This is reported as bug 15306 in the Songbird Bugzilla – would be nice if they fix that at some point.
